But what about the IR emission of the co2?
That should be isotropic.... and I guess is the part responsible for the warming we feel on the surface. Thermodynamics would argue that it must be less than that which is absorbed.
How much less? If the Earth were plane, half would go to space, and half would go back to Earth.
Since the Earth is a sphere, more than half goes to space... how much? bah... might be the difference is negligible, compared to the flat earth model.
